    text
    copied!<p>I'm building a Drupal module to tie an icon to a particular page using an administration form. Each image placed within a certain directory needs to be output with a select box next to it showing all the primary link titles.</p> <p>I've built the form using a <code>foreach</code> loop but when I check the output using <code>dpm($form);</code> in the _submit function the #value for each images page element is always equal to what ever is set for the last image.</p> <p>Here's my code:</p> <pre><code>function titleicon_admin_settings() { $settings = variable_get('titleicon_settings', $default); //build an array of primary link titles $primary_links_items = menu_primary_links(); foreach ($primary_links_items as $item) { $title = $item['attributes']['title']; $href = $item['href']; $titles[$href] = $title; } //build array of icons $directory = file_directory_path() . '/icons'; $mask = '(jpg|jpeg|gif|png|JPG|JPEG|GIF|PNG)'; $icons = file_scan_directory($directory, $mask); foreach ($icons as $icon) { $name = $icon-&gt;name; $path = base_path() . $icon-&gt;filename; $html = '&lt;img src="' . $path . '" width="50" height="50" /&gt;'; $default_value = $settings[$name]['page']; $form[$name] = array( '#type' =&gt; 'fieldset', '#title' =&gt; $name, ); $form[$name]['path_to_icon'] = array( '#type' =&gt; 'value', '#value' =&gt; $path, ); $form[$name]['icon'] = array( '#type' =&gt; 'markup', '#value' =&gt; $html, ); $form[$name]['page'] = array( '#type' =&gt; 'select', '#title' =&gt; t('Show icon on page'), '#default_value' =&gt; $default_value, '#description' =&gt; t('Choose which page to show icon on.'), '#options' =&gt; $titles, ); } $form['submit'] = array( '#type' =&gt; 'submit', '#value' =&gt; t('Save'), ); return $form; } </code></pre>
